Variables | |
msg_hclass_t | sip_accept_class [] |
Header class for Accept header. | |
tag_typedef_t | siptag_accept |
Tag for Accept header object. | |
tag_typedef_t | siptag_accept_str |
Tag for string with Accept header value. | |
#define SIP_ACCEPT_INIT | ( | ) |
Initializer for structure sip_accept_t.
A static sip_accept_t structure for Accept header must be initialized with the SIP_ACCEPT_INIT() macro. For instance,
#define SIPTAG_ACCEPT | ( | x | ) |
Tag list item for pointer to a Accept header structure sip_accept_t.
The SIPTAG_ACCEPT() macro is used to include a tag item with a pointer to a sip_accept_t structure in a tag list.
x | pointer to a sip_accept_t structure, or NULL. |
The corresponding tag taking reference parameter is SIPTAG_ACCEPT_REF().
#define SIPTAG_ACCEPT_STR | ( | s | ) |
Tag list item for string with Accept header value.
The SIPTAG_ACCEPT_STR() macro is used to include a tag item with a string containing value of a sip_accept_t header in a tag list.
s | pointer to a string containing Accept header value, or NULL. |
The string in SIPTAG_ACCEPT_STR() can be converted to a sip_accept_t header structure by giving the string s has second argument to function sip_accept_make().
The corresponding tag taking reference parameter is SIPTAG_ACCEPT_STR_REF().

inline |
Copy a list of Accept header header structures sip_accept_t.
The function sip_accept_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next
) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.
home | memory home used to allocate new structure |
hdr | pointer to the header structure to be copied |
When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.
|
inline |
Duplicate a list of Accept header header structures sip_accept_t.
Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next
) to a list of headers, all the headers in the list are duplicated, too.
home | memory home used to allocate new structure |
hdr | header structure to be duplicated |
When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.
|
inline |
Make a Accept header from formatting result.
Make a new sip_accept_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_accept_t.
home | memory home used to allocate new header structure. |
fmt | string used as a printf()-style format |
... | argument list for format |
|
inline |
Initialize a structure sip_accept_t.
An sip_accept_t structure for Accept header can be initialized with the sip_accept_init() function/macro. For instance,
|
inline |
Make a Accept header structure sip_accept_t.
The function sip_accept_make() makes a new sip_accept_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.
home | memory home used to allocate new header structure. |
s | string to be decoded as value of the new header structure |
|
inline |
Test if header object is instance of sip_accept_t.
Check if the header class is an instance of Accept header object and return true (nonzero), otherwise return false (zero).
header | pointer to the header structure to be tested |
1 | (true) if the header is an instance of header accept |
0 | (false) otherwise |
|
extern |
Header class for Accept header.
The header class sip_accept_class defines how a SIP Accept header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_accept_t header structure.
